Mine is OOO for Out Of Office. I always misread it in my head like a ghost and it takes me a few seconds to process. It also doesn’t translate to speech—you have to say the whole thing.
Interested to see if others have similar acronyms they beef with.
I don’t think that’s an acronym, it’s just an abbreviation
But then why is it pronounced “eye dee” as if each letter stood for a separate word, and not “eyed” as if it was a short hand, like every other abbreviation?
